Dimensions LV 100-3000 (in mm. 1 mm = 0.0394 inch)
Remarks
IS is positive when VP is applied on terminal +HT.The primary circuit of the transducer must be linked to the
connections where the voltage has to be measured.This is a standard model. For different versions (supply
voltages, turns ratios, unidirectional measurements...),please contact us.
Secondary terminals
Terminal + : supply voltage + 15 VTerminal M : measureTerminal - : supply voltage - 15 VTerminal : ground or earth
Connection
LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
Mechanical characteristics
General tolerance 0.3 mmFastening 2 holes 6.5 mmConnection of primary M5 threaded studsConnection of secondary Faston 6.3 x 0.8 mmConnection to the ground M5 threaded studFastening torque 2.2 Nm or 1.62 Lb. -Ft.
